The AirTAC AirTAC SDA40X160B Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 160mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA40X160B is a double-acting, single-rod compact cylinder engineered with a 40mm bore and a 160mm stroke. It generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa, making it suitable for medium-duty positioning tasks. Because this specific stroke exceeds the 130mm maximum standard length for this bore size, it is manufactured as a non-standard, made-to-order unit.
This model features a male M14x1.5 piston rod thread for secure mechanical coupling to your load. The short, riveted aluminum body minimizes axial mounting depth compared to conventional round-body units. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorbers. Note that this SKU lacks a piston magnet and therefore cannot support magnetic sensing.

Actuates a routing flap on a logistics sorting line, utilizing the 628.3 N push force to redirect parcels weighing up to 32 kg smoothly onto secondary chutes.
Drives the folding and sealing head on an end-of-line packaging machine, where the male M14x1.5 rod end securely attaches to the pressing plate assembly.
Adjusts the tensioning roller on a weaving loom, taking advantage of the 160mm extended stroke to maintain consistent fabric feed during operation.
When sizing this actuator, consider stepping down to the SDA32, which yields 402.1 N of push force at 0.5 MPa, or moving up to the SDA50, which provides 981.7 N at the same pressure. Based on the 628.3 N push figure at 0.5 MPa, the computed safe working load is approximately 377 N (operating at a 60% margin), translating to a vertical lift capacity of about 32 kg with a 2:1 safety factor. To order, confirm the 40mm bore, 160mm non-standard stroke, PT1/8 port, male M14x1.5 rod thread, and the absence of a sensor magnet. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 40mm bore cylinder delivers 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need to select the -S option variant to enable magnetic sensing. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
